Customer Reviews (4.6 / 5 · 5 reviews)

Olivia ★★★★★

Bought these for a jig I’m building and the 600-piece pack feels like it’ll last me years. The Class 8.8 steel is reassuringly sturdy, and the zinc plating’s held up fine so far without any rust.

George Z. ★★★★★

I’ve been using these M3 screws for a few jig builds and they seat perfectly every time. The class 8.8 alloy steel feels noticeably tougher than the standard stuff I’d used before.

Jacob ★★★★★

Finally found a batch of M3 screws that actually hold torque without stripping. The hex socket drive and zinc plating make these perfect for my jig builds.
